The 1977 FNCTC car was simply red white and blue. You only need to paint the car white and my decals will do the rest The 1978 FNCTC was DAYGLO red, white and blue. Since I can't print dayglo, you will need to paint it. yourself - my decals come with a masking template that matches up perfectly to the blue ares they butt-up against.
The 1979 Bud car is red white and blue but arranged in such a way that the red needs to be painted in some areas - like the engine cover. Since I cannot match my decals to red paint, I am not including any of the red and I am again supplying a masking template. Also note, these are for the narrow nose that ran at Indy.
